Creating PDF files for documents using a non-Roman character set

You can write and typeset SWP and SW documents in languages that use a
non-Roman character set (such as Japanese or Simplified Chinese) in two ways.
You can

Typeset PDF documents using XeTeX, an adaptation of TeX
that is available with TeX Live, which includes support for many languages.
Typeset DVI documents are not available with XeTeX.

Create DVI documents using the Lambda system, which is
provided with Versions 4.x and 5.x of SWP and SW, and then create a PDF file
from the document using Adobe Acrobat Distiller. Because there is no pdfOmega
program, creating a PDF file from your Lambda document isn't possible
from within SWP or SW (Version 5.x).

Using XeTeX

Shells for using XeTeX to produce documents in Russian, Greek, Japanese,
Korean, and Traditional and Simplified Chinese are available in the most
recent builds of SWP and SW and also on this website.
The shells include the word 'XeTeX' in the name and contain additional
information.
